DST centi-T

Simple in Use, From Setup to Data Retrieval

The logger and the accompanying items are designed for ease of use throughout the research process, from setting up the logger, attaching it, to retrieving and analysing the data. The logger is supported by the SeaStar software and a Communication Box which have to be purchased with the first order.

Setting up the Logger

To launch the logger for measuring it is placed into the Communication Box interface that connects with a USB cable to a PC computer. In the SeaStar software, the user sets the start time, start date and sampling interval before starting the logger in measurement mode. The logger synchronizes its internal clock with the date & time on the computer being used.

Single or multiple intervals

There are two modes for sampling, either at a single interval throughout the period or multiple intervals. When choosing multiple intervals programming it is possible to define up to seven different intervals and number of measurements for each interval. Shifting between wide and narrow intervals can help in extending the measuring period due to memory limitation and have more frequent measurements during certain time periods.  

Memory and Battery Life Calculations

The software automatically calculates when memory fills based on certain interval settings, making it easier for the user to decide how to program the logger. Estimation on battery consumption during that time period is also calculated.

Uploading the Data

After recovering the logger, it is inserted into the communication box and the recorded data is uploaded to the software. The results are displayed both in graphic and tabular form and the data can be exported to other programs. The time series data shows each measurement with its own time stamp.

Low energy consumption

After data retrieval the logger can be reused, as long as the batteries inside last. Battery life estimation is always reported upon connection with the logger. Due to the low energy consumption circuitry design the battery life is long, but actual lifetime depends on usage and sampling interval used.

*Outside ranges available upon request.
**For sampling interval of 10 minutes.
Warranty: 12 months.
Specifications may change without notice.

Communication box

The Communication Box serves as an interface between the DST and a PC computer. It is used for connecting to the DST, when starting the logger and retrieving data. DST is inserted into the hole of the box for wireless communications. The box comes with a USB cable for connecting to a PC computer. 

SeaStar software

The SeaStar software for Windows is needed to operate the DST. Data is displayed in a graph and table. The time series data file can be opened in other programs. An installation product key is provided when ordering the software, for online downloading. 

Plastic protective housing

Star-Oddi offers protective housing for the DST to give more flexible mounting options and to protect the data logger when used under more harsh environmental conditions. When used as a stand alone logger it can be attached to fishing gear, moorings, deployment lines or other equipment. It has attachment points (6 mm in diameter) on top and bottom. The protective housing is made of polyurethane (PUR) plastic. The housing dimensions are 75 mm in length x 30 mm in diameter. Weight is 50 g in air and 10 g in water. 

Wire clip for plastic protective housing

This is ideal for fastening the equipment to fishing gear and long lines. The wire fasteners are made of non-corrosive stainless steel with a clip to ensure secure fastening. The length of the wires can be adjusted to fit the application.

Stainless steel protective housing for DST

Star-Oddi offers stainless steel protective housing for DST loggers. We recommend using them along with a plastic housing to give extra protection. It is ideal when the logger is being used on large trawls or in situations where the bendable plastic housing would not give enough protection. Dimensions of the steel housing are 125 mm x 42.4mm. Thickness is 3.25mm and it weighs 356 g in air.
